Low Level Virtual Machine (LLVM) is:
- A compilation strategy designed to enable effective program
optimization across the entire lifetime of a program.
- A virtual instruction set.
- A compiler infrastructure.
- LLVM does not imply things that you would expect from a high-level
virtual machine. It does not require garbage collection or run-time
code generation.

Apply several upstream svn revisions that have also been merged to the
base version:
r170353:
Fix another SROA crasher, PR14601.
This was a silly oversight, we weren't pruning allocas which were used
by variable-length memory intrinsics from the set that could be widened
and promoted as integers. Fix that.
r175057:
X86: Disable generation of rep;movsl when %esi is used as a base pointer.
This happens when there is both stack realignment and a dynamic alloca in the
function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the

Add a new option MANPAGES to allow man pages to be supressed. [0]
Remove USE_GCC=4.2+ as all supported versions have an acceptable version
of gcc by default.[0]
Remove the long unused MAINTAINER_MODE variable.

Upgrade the LLVM and Clang -devel ports to r133062.
Update the conflicts lines in all the llvm and clang ports to conflict
with 3.x as well as 2.x and generally simplify the conflict definitions
following the example of llvm-etoile.

Build fails on ia64 with:
/work/a/ports/devel/llvm/work/llvm-2.6/Release/lib/libLLVMJIT.a(JIT.o)(.text+0x1231):
In function `llvm::JIT::JIT(llvm::ModuleProvider*, llvm::TargetMachine&,
llvm::TargetJITInfo&, llvm::JITMemoryManager*, llvm::CodeGenOpt::Level, bool)'::
undefined reference to `__register_frame'
Given the lack of a backend for IA64, I can't give fixing it a real high
priority.

Depend on dejagnu if either PACKAGE_BUILDING or MAINTAINER_MODE are set so
the regression tests get run on the package cluster. Make regression-test
depend on build. Remove an extra blank line.

Upgrade LLVM to release 2.3.
In theory this should build on every architecture so remove the
no-sparc64 bit.
Add a MAINTAINER_MODE option to allow debug (very slow) versions to be built
and a regression-test target. [1]

Upgrade devel/llvm and lang/llvm-gcc4 to LLVM 2.2.
Switch llvm-gcc4 from the deprecated gcc 4.0 based version to a new gcc
4.2 based release.
See the release notes for details:
http://www.llvm.org/releases/2.2/docs/ReleaseNotes.html

Upgrade to LLVM 2.1, the latest release.
A couple patchs are included from HEAD that didn't make the release, but
fix use-after-free bugs.

Upgrade to LLVM 2.0.
From the release notes: "This is the first LLVM release to correctly
compile and optimize major software like LLVM itself, Mozilla/Seamonkey,
Qt 4.3rc1, kOffice, etc out of the box on linux/x86"
